3. Step-by-Step DIY Repair Guide for Lincoln Nautilus
Read ECT live PID on scanner. If it reads 284°F (140°C) or higher with engine cold, a short to ground exists. on the Lincoln Nautilus equipped with 2.0L EcoBoost (250HP) / 2.7L Twin-Turbo V6 (335HP Black Label).
Unplug sensor connector while watching live data. If temperature drops to -40°F (-40°C), the sensor itself is shorted. on the Lincoln Nautilus equipped with 2.0L EcoBoost (250HP) / 2.7L Twin-Turbo V6 (335HP Black Label).
If reading stays pegged at max with sensor unplugged, inspect harness for pinch points grounding against engine block. on the Lincoln Nautilus equipped with 2.0L EcoBoost (250HP) / 2.7L Twin-Turbo V6 (335HP Black Label).
Allow engine to cool, unscrew old ECT sensor from coolant crossover pipe or thermostat housing, install new OEM sensor with fresh thread sealant. on the Lincoln Nautilus equipped with 2.0L EcoBoost (250HP) / 2.7L Twin-Turbo V6 (335HP Black Label).
Bleed air from cooling system, clear DTCs, and verify normal temperature rise on live data. on the Lincoln Nautilus equipped with 2.0L EcoBoost (250HP) / 2.7L Twin-Turbo V6 (335HP Black Label).

4. Lincoln Nautilus P0117 FAQs
What causes code P0117 to trigger on a Lincoln Nautilus?
On the Lincoln Nautilus (2.0L EcoBoost (250HP) / 2.7L Twin-Turbo V6 (335HP Black Label)), P0117 is most frequently caused by ECT sensor internal short to ground or Short circuit to ground in ECT signal wiring harness.
Where is the OBD-II port located on my Lincoln Nautilus?
On the Lincoln Nautilus, the 16-pin DLC diagnostic connector is located Under driver side steering column. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Lincoln Nautilus with code P0117?
No. The ECU thinks the engine is at 280°F+ (overheating) and runs rich or disables cooling fan logic. Given that P0117 carries a High severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
